Minor nit here.

At least before this is final I would really appreciate if you could
rebase this on top of my unificiation of siginfo.h that I posted on
linux-arch and is in my siginfo-next branch.

As that already pushes NSIGFPE up to 13.

Which would make this patch change NSIGFPE to 14 and allocate the number
14 for FPE_UNKNOWN
